Merge branch 'for-linus' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe:
"This contains a set of fixes for xen-blkback by way of Konrad, and a
performance regression fix for blk-mq for shared tags.
The latter could account for as much as a 50x reduction in
performance, with the test case from the user with 500 name spaces. A
more realistic setup on my end with 32 drives showed a 3.5x drop. The
fix has been thoroughly tested before being committed"

Well with wlan0 it was working also for me as I wrote there. Could you please setup eth0 and do same test? Two users of ArchLinxArm with mainline kernel did reported this, thus I would like to know this from an buntu User.

thank you for sharing. I've just tried a mainline kernel built upon this config (I assume you are using the meson-gxl-s905x-khadas-vim.dtb), but I still experience these strange network issues. You may try it by yourself by cloning the Linux source code repository via git, e.g.
